Answer:
Two
Step-by-step explanation:
The table is saying that, if Sandra swam enough races, she should expect to get 20 firsts, 12 seconds, 6 thirds, and two no placements.
Her expected value of points will be the average (mean) of all the points awarded for each race.
The average is the total number of points divided by the number of races.
The simulation says that, if she swam 40 races, she should expect to earn a total of 90 points.
She can't win a fraction of a point, so she can expect to win two points in her first race.
Answer:
Wow, I'm learning this in class right now lol, the answer is C, 42cm cubed.
Step-by-step explanation:
The formula for finding volume fo 3d shapes is area of base x height/length.
In this problem, they give you both of those. 14 x 3 = 42, so the answer is C.
Hope this helped! If it did, please give me brainliest! It would help a lot! Thanks! :D

<h2>The height of the rocket increases for some time and then decreases for some time.</h2>
The height from the ground increases from 4 to 26, then decreases from 26 to 0.
Why the others are wrong.
A. The height of the rocket changes at a constant rate for the entire time.
The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.
C. The height of the rocket remains constant for some time.
The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.
D. The height of the rocket decreases for some time and then increases for some time.
This implies the graph decreases first then increases. However, the rocket will increase, then decrease.
